The Myphone MY81 is an ultra-budget smartphone from 2016, primarily available in the Philippines. It is powered by a Spreadtrum SC7731 chipset and operates on Android 5.1 Lollipop. The device’s functionality is severely limited by its hardware, most notably its extremely low 512MB of RAM. This leads to a variety of software problems, including getting stuck on the Myphone logo (bootloop), constant app crashes, and performance so poor that the phone becomes unusable. For owners facing these issues, a full reinstallation of the stock firmware is the only effective method to restore basic functionality.
This guide provides the official .pac firmware for the Myphone MY81. The installation must be performed using the SPD Upgrade Tool on a Windows computer.

Why Flash This Specific Firmware?
Based on reports from Filipino tech forums and user communities, flashing the stock ROM is the best solution for these specific Myphone MY81 problems:
- Fix Bootloop (Hang on Logo): This is the most common reason users need this firmware. If your phone won’t start past the Myphone logo, flashing this file will repair the corrupted operating system.
- Remove Persistent Viruses and Malware: Due to its user base, this device is a common target for malware distributed through third-party apps. A full firmware flash is the only guaranteed way to remove it.
- Solve Constant “Unfortunately, App Has Stopped” Errors: The 512MB of RAM and software corruption lead to frequent app and system crashes. A clean installation provides a stable environment and resolves these errors.
- Restore Basic Usability: Flashing the firmware can make the difference between a frustratingly slow, unusable device and one that can reliably perform basic tasks like calls, texts, and light browsing.
- Prepare for FRP Lock Bypass: If you are locked out by Google’s Factory Reset Protection, installing the stock firmware is a crucial first step to ensure the system is clean before you attempt a bypass.
